Abstract
Three-dimensional (3D) graphene-based nano composites have attracted significant attention for energy storage and conversion applications. In this study, Simonkolleite nano platelets (SMNPs) were deposited on 3D nickel foam-graphene (NiF-G) by a rapid microwave-assisted hydrothermal method to form NiF-G/SMNPs nano composite electrode material. Field emission scanning electron microscope (FE-SEM) of the NiF-G/SMNPs electrode revealed that the SMNPs were evenly distributed on the surface of NiF-G and interlaced with each other, resulting in a higher electrochemical performance compared to NiF-G and NiF/SMNPs. Utilizing this composite material, a super capacitor with a specific capacitance of 836 F g-1 at a current density of 1 A g-1 has been achieved.
